‘Huge amount of CO2’ from Himalaya’s geothermal springs: The hot water springs in the Himalayas, one of the world’s most famous tourist destinations, release a ‘huge amount of carbon dioxide’.
A new study by the Wadia Institute of Himalayan Geology has found, which suggests the decarbonation process of carbonate rocks which are present deep in the Himalayan core, along with oxidation of graphite is the source of carbon dioxide in the thermal springs.
After carrying out a detailed chemical analysis of water samples collected from 20 geothermal springs from major zones of Garhwal Himalaya, the scientific team found that the water contains high levels of dissolved inorganic carbon.
Simple compounds such as carbon dioxide is where primarily inorganic carbon is found.
Published in the journal Environmental Science and Pollution Research the study also notes these geothermal springs have the potential to emit to the atmosphere around 7.2 × 106 mol of carbon dioxide every year.
Such carbon dioxide emissions should be taken into account to assess global carbon discharges in the earth’s atmosphere, the scientists of the institute, which runs under India’s Department of Science and Technology, argue.
Himalaya is home to around 600 geothermal springs, which have varied temperature and chemical conditions.
